[Kst] [Kst-plot/kst] 5be7ab: graphics system needs to be set before QApplicatio...

[Nicolas Brisset]

Nice try, but when I do this (OpenSUE 13.1 with NVIDIA binary drivers) I get empty menus (translucent boxes). 
The rest seems to work (dialogs) but I haven't looked further neither checked performance as this would be a no-go.
Can you see the same effect?

I also checked the Qt doc and found this:

void QApplication::setGraphicsSystem ( const QString & system ) [static]
Sets the default graphics backend to system, which will be used for on-screen widgets and QPixmaps. The available systems are "native", "raster" and "opengl".

There are several ways to set the graphics backend, in order of decreasing precedence:

the application commandline -graphicssystem switch
QApplication::setGraphicsSystem()
the QT_GRAPHICSSYSTEM environment variable
the Qt configure -graphicssystem switch
If the highest precedence switch sets an invalid name, the error will be ignored and the default backend will be used.

Warning: This function is only effective before the QApplication constructor is called.

Note: The "opengl" option is currently experimental.

So I don't know how it works for marble, but I'm not sure this is the right way to do it. Maybe we rather need to check the QGraphicsView doc...
